Original application filed August 11, 1908, Serial No. 447,968. Divided and this application filed February To all whom'it may concern:

Be it known that we, BENJAMIN Annmnon and Arms CALLnsoN, citizens of the United States, residing in Brooklyn, borough of Brooklyn, New York, have invented certain new and useful Improvements in the Method of Sealing Bottles; and we do hereby declare the'followin to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference markedthereon, which form a part of this specificatiom This invention relates to the sealing of' bottles by means of flanged caps, and it consists in certain improvements in the method utilized in this art which distinguish from prior expedients'in the following principal ways:

v In the improved sealing head herein shown and described the contraction of the lower or edge part of the cap-flange, whereby to bend 1t under and into locking engagement .with the shoulder on the bottle, is accomplished by an annular series of aws each in the form of a bell-crank lever having one:

, on the bottle. The cavity produced by the jaws being initially approximated to the initial diameter of the cap and each jaw having its axis of movement or fulcrum rela-' tively near its acting or bending facejor edge, it re uires but slightmovement of the jaws to e ect the interlockingof'the cap to the bottle head, and, in addition, the edge part is by a drawing, as well as by a bending, action forced under the shoulder on the bottle-head, whereby a more substantial grip of the cap on the headis obtained than by merebend ing, and the danger of crushing the head is reduced. The improved sealing-head is further so constructed that, inthe applying of caps having corrugated flanges, commonly known as Crowns, its cap-bending portions lmplnge on thelnner oorrugatlons of 20, 1909. Serial No. 479,032.

the cap-flange; so far as we are aware, the

method of sealing bottles thus involved in the use of our improved sealing head is new and it entails the following advantage, to wit, the uniform inward displacement of the edge part of the cap and a consequent even distribution of pressure ofthe cap flange on the bottle shoulder, annularly thereof, which results are not 1n practice possible in the method previously employed where, the bending'portions being intended to operate upon all the outer corrugations of the cap,

Fig. 2 is a vertical central sectional view of the improved sealing-head and of a cap, the head of a bottle about to be closed by the they almost invariably only impinge against a part of them ;'it entails the further advancap and certain parts of the sealing-head apv pearing in elevation, and the bottle, cap and the parts of the sealing-head being' shown in their first position; Fig. 3 is a view substantially similar to Fig. 2, except that a part of the bottle-head appears'in section, the parts being in their second position; Fig. 4 is a view similar to Fig. 3, the parts being in their third position; Fig. 5 is a vertical sectional view of the closed bottle-head;

6 is an underneath plan view of the sealinghead; and, Fig.1 and Fig. 8 illustrate details of the sealing-head, Fig. 7 being a vertical sectional view and Fig. 8 anelevation.

\ r 9' V In F1 1 is shown a bottle-seahng or closing mac me a provided with the improved scaling-head I) and with suitableimeans c for raising a bottle A and causing its mouth to impinge against the cork lining e of a cap f, having a corrugated flange, and thereupon forcing the fcap upwardly against means in the sealing-head whose first operation is to produce a sealing or closing contact between I the mouth of the bottle and the lining of the cap and whose second operation-is to secure the cap to the bottle-head b' interlocking the cap-flange with the shoul er on the bot tle-head.

The improved sealing-head comprises a hollow stem 9- havin internal threading. h ed at its upper end an an exterior threa flange-z at its lower end; .aplug being screwed into its upper end. and a cylindrical socket 7:: being screwed onto its lower end andlhaving' an internal shoulderl at the bottom theneof. The socket receives a ring-m having an external shoulder n which abuts against. the shoulder-Z, and it also= receives a ring 0 which has an external flange 0 projecting between the ring m and theflange z of the stem g; The ring 0 snugly fits the ring m, and has the radial slits p-coinciding with the semi-circular radial recesses g in the ring m, one recess for each jaw (Fig. 6). To facilitate the assembling of the parts, the pilpg 0g) is preferably. split diametrically Iii bheslits p and therecesses q are anran d the jaws 1'. Each jaw is substan-- tial y a lever provided with an inwardly projecting arm 3 and with a bearing-portion 6 of; substantially semi-circular form, such bearing p'ortion being of the same ra-- dins asthat of the necessesg.- Each jaw has a shoulderu which abuts against a shoalder 4) on the ring on below its recesses, such shoulderscooperating to limit the retracting movement of the jaws. The jaws arenor mally held retracted, their shoulders at being in contact with: the shoulder o of ring. m, by a! follower to which bears down upon their arms 8' and is under the-pressure of a s'piral-sprin m arranged in the stem gand interposed: etlween said. follower and-the plug j;;.=the tension of the spring may be'adjusted by manipulating the plug j. The fol-- lower moves vertically in-rm '0.

On referring to Fig; 6 it wi l be'seen that the acting portionsyof the jaws rare spacedfrom each other at intervals corresponding with thespaces between'the inner corrugations of the-cap f further, that such acting portions are rounded, and that the diameter of the circle representedby the acting por tionsy of the j awsin their rest position approximates the diameter of the inner corrugationsof the cap, or is at least less than the diameter of the outer corrugations of the cap. Thus, when a cap of the crown type is thrust into the cavity formed by the annular series of jaws, thecap is compelled to occupysuch a relation to thejaws that .the acting portions 1 of the latter enter bet Weenits outer corrugations andare diirctly opposed to itsinner corrugations.

The operation is substantially as follows: cap being arranged-above the bottle A, and being held by anysuitable means, such the metal downwardly so that the. a

the outer hes 19s i,,..i.", as .2 1n Fi 2, the mechanism 0 is caused to raise the hbttle A 80- that itfirst. impinges jenter between the acting portions y of the jaws 1'. Upon the upward movement of the bottle andcap being continued, the cap impinges against the arms 8 of the jaws, and,

the tension of spring w being overcome, the

jaws turn in their'bearings; formed by therecesses Q, and thereby' e their acting portions moved into a -more contracted relation. During this part of theaction and up to thetime that the bottle and cap cease their upwardmovement, the jaws not only act to bend the flange-edge under'the shoulder-B on thehead 'of the bottle A but ldrgw e etween'the top 1 and the'fiange 2 oft e cap assumes more or less the form: of a curve (see Fig; '5). The ultimate result isthat the caps are: more firmly or positively interloelied witlr bottle-heads when attached inaccordance with this invention, so thata lighter grade of stock inthe metallof the cap'ma-ybeused; a

It will be. understood tliat the circle in which the axis of movement (approximatelythe point C) of each jaw lies-is relatively close to the clrcle Vertically coinciding with theacting-portions got the jaws, so that comparatively little movement of each jaw is required inorder to cause it to force into interlocking relation the cap flan with'the bottle-shoulder. Also that, because each jaw has arecess 3 receiving what is refierred to is accentuated and the wholeof art. of the cap drawn into closer relation wlth the mouth of the bottle, producing thereby a condition of compression in the lining'of the cap which is greater both in'degree and in extent of'area than it would otherwise be. l
